Ventalation for a switchgear room
Ventalation for a switchgear room
(OP)
I need to keep a switchgear room clean in the middle of the coal handling yard of a coke plant.
Any ideas on a positive preasure system?
The room is 20ft x 40ft with one 1500kva dry type transformer as part of a 4160/480 single ended unit substation.

Can you seal the room well then provide dry plant air with pressure control like those used in clean rooms to keep the rooms a few millimeters above the atmospheric pressure.
What are you thinking?

The coal dust is almost like talcum powder and had built up on horizontal surfaces and transformer bracing. We cleaned and tested the equipment after it had been in service for about 18 monthes and there was an inch of dust on all surfaces. Had the primary voltage been 13kV rather than 4160 volts there would have been a flash over.
No matter what is installed there will be constant maintenance of the filter elements.
We used a similar rolling filter system in the steel mill for filtering large motor cooling air.
The best solution would have been the owner not putting the switchgear next to the rail car loading conveyor!!!!

I am searching for a manufacturer of rolling filter material since the trick seems to be put the room under a positive preasure with CLEAN air.
